Freeware CurvFit
Fit w/ Sine, Power, Exp., + Lorentzian Series.
CurvFit (tm) is a curve fitting program 4 Windows. Lorentzian, Sine, Exponential & Power series are available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple peaked/valleys data. CurvFit is another improved productivity example do to using Calculus (level) programming ... ie. minutes to solve, days or years to understand solution & what it implies (e.g. wrong model, sampling rate error).

Offers linear/non-linear least-square fitting.
Power-Surface offers linear/ quadratic/ higher-power least-square curve/ surface fitting for the given column-wise numeric data for a function z = f(x) or z = f(x,y) of one or two independent variable(s), so that the fitted function is of the form z = a + b.x + c.x2 +... or z = a + b.x + c.y + d.x2 + e.xy + f.y2 +... respectively (refer to tutorials). The Saw-File subroutine allows vertical copying/pasting of numeric data columns from text files.
